Claims. (Cl. 4-7) This invention relates to new and useful improvements n water closets and more particularly to a water closet mcorporating a bidet.

An object of the invention is to provide a water closet having a nozzle so positioned as to discharge a stream of water forwardly on the center-line of the closet bowl and between the buttocks and into contact with the body of a person using the closet in order to wash the anus.

Another object is to provide a bidet in which the domestic water supply will be free of contamination from the closet bowl.

Another object is to provide a gentle discharge from the nozzle which will have a predetermined limited upward and forward trajectory.

Theinvention consists in the novel arrangement and interrelation of parts to be more fully described hereinafter and the novelty of which will be particularly pointed out and distinctly claimed.

In the accompanying drawings, to be taken as a part of this specification, there is fully and clearly illustrated a preferred embodiment of the invention, in which drawrngs:

Fig. 7 is an enlarged detail view in section on the line 77-of Fig. 6.

Referring to the drawings by characters of reference, the numeral 1 designates the closet bowl of a water closet having a base 2 and a hollow flushing rim 3 with a passageway 4 therethrough. The rim passageway 4 distures 5 which surround the bowl 1. In the bottom of the bowl there is an outlet 6 leading through a water trap 7 to a downward directed outlet passage 8. The hollow rim 3 has. a vertical continuous inner wall 8 and has a rear portion 9, a front portion 10, and intermediate side portionslland 12 which curve downward from the front and rear portions. Overlying the rim 3 there is a seat 14 having an open front end and which is pivotally mounted at its rear portion on hinge members 15 in the usual manner. The rear seat portion 14* extends forward of the rear rim portion 9 in overlying, protecting relation thereto.

The bowl 1 has a hollow horizontal rearward extension or shelf 16 which overlies the trap 7 and passage 8 and extends rearwardly from the rear rim portion 9. Within the'hollow shelf 16 there is a passageway 17 formed between vertical walls 18 and 19 and opening at its discharge end into the rim passageway 4. At its other end, the passageway 17 has a flushing opening 20 through its top wall.

Mounted on the shelf 16 there is a water supply or flush tubular fitting 22 The outlet 22 is controlled by a flush valve 23 which seats on the fitting 22 and is operable by a trip lever 24 and lift mechanism 25. The lever 24 is pivoted in an opening through the tank front wall above the level of the top of the tank overflow pipe 26 which discharges into the outlet 22 beneath the valve 23 in the usual manner. Water is supplied to the tank 21 from the domestic cold water supply through a pipe 27 which is sealed in and through the tank bottom wall and extends upward within the tank to a point above the maximum water level therein which is determined by the open top end of the overflow pipe 26. Water discharge from the pipe 27 is controlled by a float operated valve 28 mounted on the upper end of the water supply pipe 27. The valve 28 has a downward discharging outlet pipe 28 which terminates adjacent the bottom wall of the main chamber 32. The valve 23 may be of any well-known construction having an operating float 29, the valve 28 being shut by the float 29 when the Water level reaches the line LL in the tank 21.

Within the tank 21 there is a partition or wall 30 extending from the tank front wall to the tank rear wall and'terminating at its horizontal top edge 31 below, but adjacent, the tank liquid level L-L. The partition 30 divides the tank internally into a main chamber or compartment 32 and a supplemental chamber or compartment 33. The main chamber 32 has the outlet 22 for the bowl flushing water and also contains the supply pipe 27 and the float 29. When the main chamber 32 fills with water from the open valve 28 through the outlet pipe 28 the water will overflow the partition top edge 31 and fill the supplemental chamber 33 before the float 29 shuts the valve 28. When the valve 28 is shut off,

water will stand in both chambers to the line L-L.

Through the bottom wall 34 of the supplemental chamber 33 there is an outlet 35 through a tubular fitting 36 sealed in the bottom wall 34. Connected and sealed into the outlet end of the fitting 36 there is a pipe 37 which leads to the inlet 38 of a plug type angle valve or cock "-39 supported and secured in an opening 40 through an .55 charges downward into the bowl through a series of aperexterior vertical flange or wall 41 of the shelf 16. The valve 39 has a handle or operating lever 42 connected by a rotary stem 43 to the valve member 44 which has a port 45 rotatable into and out of registry with the inlet- 38. In the valve member 44 there is a longitudinal bore or passage 46 into which the port 45 opens and which discharges to the valve outlet 47. Connected into the valve outlet 47 and sealed therein, there is one end 48 of a pipe 49 which passes through an opening 59 in the wall 18 and into the water flushing passageway 17. The

opening 50 is sealed around the pipe 49 by a rubber sleeve 51 surrounding the pipe and held under compression between nuts 52 threaded onto the pipe 49. Within the passageway 17, the pipe 49 is bent or turned at a right angle so that its end portion 53 is directed horizontally forward. Through the vertical wall 8 of the rear rim portion 9 on the front to rear center-line of the bowl 1 there is an opening or aperture 54 into which the pipe portion 53 extends. Screw-threaded on the pipe portion 53 there is a nozzle or jet member 55 having an orifice or discharge port 56 and a surrounding flange 57 which overlies and abuts the Wall 8 of the rim portion 9 around the edge of the opening 54. Tightly fitting on the pipe portion 53 within the opening 54, there is an expansible Patented Sept. 11, 1956 rubber sleeve or plug 58 which is expanded to seal the opening 54 by a compression nut 59 screw-threaded on the pipe portion 53. The Orifice or port 56 is inclined upwardly and forwardly on the longitudinal or frontto-rear center-line of the bowl 1 at an angle of about 35 to the horizontal. The orifice 56 is above the level of the top of the bowl rim side portions 11, 12 so that no Water .in the bowl can reach the level of or enter the orifice 56 as the water will overflow the low side portions 11 and 12 before this can happen. The seat 14'is of the saddle type which dips or inclines downward from the front and the rear so that it has a low intermediate portion, as at 60. The water trajectory or path of discharge from the orifice 56 will be substantially as indicated at X, Fig. 2, so that it is inclined forward and upward along the front to back center-line of the seat and bowl and reaches an elevation above the low seat portion 66, but not substantially above the front and rear ends of the seat 14. The maximum head pressure of the water from the tank 21 on the orifice 56 will limit the length of the trajectory or stream so that the water stream will fall within the confines of the bowl 1 and just short of the rim front portion 10, as seen in Fig. 2.

The operation is as follows: When the closet bowl 1 is flushed by opening the valve 23 by operation of the lever 24, the water will continue to stand in the supplemental chamber 33 to the top 31 of the wall 30 so that a water supply is maintained for the nozzle 55. When the occupant of the seat 14 depresses the valve lever 42 to open the valve 39, a stream of water from the chamber 33 will discharge from the nozzle orifice 56 and wash the occupants body between the buttocks. As soon as the liquid level in the main chamber 32 falls below the line LL, the lowering float 29 will open the Water inlet valve 28. As the rate of water supplied through the valve 28 is far greater than the rate of discharge from the orifice 56, the supplemental chamber 33 will never be emptied of water, because before it can empty, water from the main chamber 32 will overflow the partition 30 to replenish the water supply in the supplemental chamber 33. If the valve 39 is opened while chambers 32 and 33 are full to the line LL, the float 29 will operate the float valve 28 to maintain the water in the tank 21 at a level above the partition top edge 31 so that the supplemental chamber 33 is maintained full of water. When the seat occupant has been washed sufficiently by the Water stream from the nozzle 55, the valve handle 42 is lifted to close the valve 39, whereupon the tank 21 will be refilled to the line LL by operation of the float 29.

Referring to Figs. 6 and 7, there is shown another form of valve for controlling the supply of wash water to the nozzle 55. Through the supplemental chamber bottom wall 34 there is an opening 70 corresponding to the opening from the outlet fitting 35. In the opening 70 there is secured and sealed a control valve having a tubular casing 71 with an external bearing arm 72. Longitudinally reciprocal in the casing 71, there is an upwardly opening valve member 73 which seats on an upward facing shoulder of an annular partition surrounding the valve port 74 to control flow of water from the valve inlet 75 to the valve outlet 76. The valve member 73 ismounted on a vertically reciprocal stem 77 which is guided in and through a sleeve member 78 screw-threaded into the bottom end of the casing 71. The sleeve member serves as a packing nut to hold a ring of packing material 79 under compression around the stem 77. The valve member 73 is urged downward to its seat by a coil spring 80 which surrounds the stem 77 and is held under compression between an upward facing stem collar and the underside of the valve port partition. The arm 72 supports a horizontal shaft 81 on which there is pivoted a vertically movable valve operating lever or handle 82 having an end portion 83 which underlies and engages the external valve stem end 84. Downward movement of the handle ber to said bowl, a conduit leading from mental chamber to said nozzle, a valve in said conduit,

82 will therefore move the lever end portion 83 upward and acting through the stem 77 will lift the valve member 73 to open the port 74. When the handle 82 is released, the spring will move the stem 77 downward and seat the valve member 73 thereby closing off flow from the supplemental 'chamber 33. Connected and sealed into the valve outlet 76 there is a pipe 85 which extends through an opening 86 in the shelf flange 41 and the opening 50 in the wall 18 of the passageway 17. The opening 50 is sealed around the pipe 85 by a rubber sleeve 87 which is expanded radially inward and outward by the compression nuts 88, 89 screw-threaded on the pipe 85. Within the flushing passageway 17, the

pipe 85 is turned or bent at a right angle to extend hori-' zontally forward for'connection of its free outlet end portion 90 into the nozzle 55 which is sealed in the rim opening 54 as above described.

The operation of the structure of Figs. 6-and 7 will be apparent from the foregoing description. However,

it may be noted that when the handle 82 is depressed to open the valve member 73, the wash water from the supplemental chamber 33 will discharge through the nozzle orifice 56 as above described for Figs. 1 to 5. When the handle 82 is released, the spring 80 will close the valve member 73 to shut off discharge of water from the nozzle 55.
